摘　　要：讨论了玄武岩粉用作水泥混合材的长期力学性能,并采用比强度法对其火山灰效应进行了数值分析。结果表明,龄期的增长和比表面积的增大都有助于玄武岩粉火山灰效应的发挥;数值分析结果表明,玄武岩活性远小于Ⅰ级粉煤灰,其单掺的适宜掺量应控制在15%以内。The influence of taking basalt as cement mixture on long-term mechanical properties was discussed,and numerical analysis of pozzolanic effect was conducted by using specific strength method. It was proved by experiment that growth of curing age and specific surface area increasing was helpful for the pozzolanic effect of basalt;the result of numerical analysis showed that activity of basalt is much less than I-level fly ash,appropriate content should be controlled within 15% when single-doped.
